SH3-DSP CPU 32-bit RISC CPU Datasheet

2020-12-16
The SH3–DSP CPU interprets and executes the SH3–DSP instruction that extended the SH-3 instruction. For multiply instructions and DSP arithmetic instructions, calculations are performed with a digital signal processor (DSP) module.
Key Features:
●Compatible with object code level with SH -1, SH -2, and SH 3
●Built-in 32-bit internal data bus
●Supports abundant register groups
■General-purpose register: Sixteen 32-bit registers (including eight 32-bit bank registers)
■Control register: Eight 32-bit registers
■System register: Four 32-bit registers
●The instruction execution time of the basic instruction corresponds to one instruction / cycle
●The logical address space corresponds to 4 GB
●Features of DSP
■Mixing 16-bit instructions and 32-bit instructions
■Supports multiplier, ALU, barrel shifter
■Built-in 32-bit one-cycle multiplier corresponding to 16 bits x 16 bits
■Supports large capacity DSP data register file
■Supports extended Harvard architecture for DSP data bus
●Peripheral circuit
■MMU, TLB, INTC, UBC, AUD, BSC, DMAC
